Dopeioklept

dopeioklept (n.) “One who steals drugs.”

Derived from the modern word “dope” as in drug and the Greek “kleptes” meaning thief. (i.e. kleptomania). The famous Word Archeologist Thoth calls it "a modern euphemism which dampens the ugly phrase drug-fiend by shrouding it in the mystery of the Greek language."
